The transition to forced operation is a jump at the DALI fade time of 0.7 s.
•
Block 1 bit: The Block function for the ballast/group is enabled. The Block function is activated by a
telegram with the value 1 and deactivated with the value 0. The ballast/group can be blocked using
this group object so that it cannot be changed via the bus.
The current brightness value of the ballast/group is frozen. Incoming telegrams are processed in the
background. Dimming processes are not simulated in the background; with time sequences the end
brightness value is immediately memorized. When the block is removed, the value updated in the
background is set.
A block during a dimming up or down process or scene operation interrupts the dimming process and
freezes the current brightness value. A block during the Staircase lighting or Slave function
immediately blocks the ballast/group and freezes the brightness value. After unblocking, the Staircase
lighting function continues in standby.
If Slave mode was active before the block, it will be re-established.
Forced operation and Block have a higher priority than manual operation.
During DALI commissioning, the Block and Forced operation functions are deactivated if the

Description
If the Forced operation group object receives a telegram with the value 0
(binary 00) or 1 (binary 01), the group/ballast is enabled and can be
controlled via various group objects.
If the Forced operation group object receives a telegram with the value 2
(binary 10), the group/ballast is forced OFF and remains inhibited until
Forced operation is deactivated.
Control via another group object is ignored as long as Forced operation is
active. Telegrams are updated in the background and the end values are
saved.
When Forced operation is deactivated the brightness value, which is
continuously updated in the background, is set.
If the Forced operation group object receives a telegram with the value 3
(binary 11), the group/ballast is forced ON at the parametrized brightness
value and remains inhibited until Forced operation is deactivated.
Control via another group object is ignored as long as Forced operation is
active. Telegrams are updated in the background and the end values are
saved.
When Forced operation is deactivated the brightness value, which is
continuously updated in the background, is set.
